Abstract: Efficient methods for wirelessly communicating file content under varying conditions are described. A wireless device determines, based on mobility and/or geographic location, if the wireless device is to operate in a first mode of communication operation in which received portions of said file are re-transmitted or a second mode of communication operation in which combinations of portions of said file are transmitted. The wireless device transmits packets communicating received file portions when it is determined that the wireless device is to operate in said first mode of operation and transmits packets communicating combinations of file portions, e.g., linear combinations of file portions, when it is determined that the wireless device is to operate in said second mode of operation. The contents of a file may be obtained from some packets which communicate distinct portions of the file and other packets which communicate combinations of distinct portions of the file.

Abstract: Methods and apparatus for reducing and/or eliminating the effect of self-interference are described. Various described methods and apparatus are well suited for use in DSRC WAVE systems in which a wireless communications device may acquire and use two DSRC channels, e.g., use one channel for reception while using another channel for transmission at the same time. A wireless communications device which is receiving a signal of interest on a first channel supports concurrent transmission on second channel, e.g., an adjacent channel. Controlled transmission timing synchronization with respect to the received signal of interest facilitates interference estimation and removal. Interference due to spillover energy from the transmission on the adjacent channel is estimated and removed from a received signal to facilitate recovery of the signal of interest.

Abstract: Disclosed are techniques for determining a motion state of a target object. In an aspect, an on-board computer of an ego vehicle detects the target object in one or more images, determines one or more first attributes of the target object based on measurements of the one or more images, determines one or more second attributes of the target object based on measurements of a map of a roadway on which the target object is travelling, and determines the motion state of the target object based on the one or more first attributes and the one or more second attributes of the target object.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform a clear channel assessment (CCA) procedure on a channel that includes multiple sub-bands of a radio frequency spectrum band. The base station may determine that the channel is available based on the CCA and transmit a special header in the channel. In some examples, the special header may include multiple transmission time intervals (TTIs), where each TTI may include a header packet in each sub-band of the radio frequency spectrum band. In some cases, the header packet may include a clear to send (CTS)-to-self frame structure. The base station may transmit a first TTI across each of the sub-bands at a first power level, and transmit additional TTIs across the sub-bands at a different power level. Additional header packets may be transmitted at the boundaries of subsequent subframes.

Abstract: Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

Abstract: Apparatus and method are provided for estimating the shortest time of arrival or the shortest round-trip time (RTT) of radio signals between communication devices in a wireless network. Filtering is performed by adaptive filters with suppressed side lobes adjustable in the time domain and widths of main lobes adjustable in the frequency domain to improve detection of signals on the shortest path of arrival or line-of-sight (LOS) path while mitigating the effects signals received from longer paths of arrival or non-line-of-sight (NLOS) paths.

Abstract: Methods and apparatus related to the sharing of wide area network (WAN) with peer to peer communication signaling usage are described. A mobile communications device receives a signal from a base station and measures a power of the received signal. The mobile communication device determines a transmission power level of a peer to peer reference signal as a function of the measured power of the received signal from the base station, wherein said function of the measured power of the received signal from the base station depends on a mobile target signal to noise ratio. The mobile communications device broadcasts the peer to peer reference signal at the transmission power level.

Abstract: Disclosed is an apparatus and method for classifying a motion state of a mobile device. In one embodiment, accelerometer data representing acceleration components along orthogonal x, y, and z axes of the mobile device are collected. A presence or absence of a half-step frequency relationship between the accelerometer data is determined. Last, the motion state of the device is determined based at least in part on the presence or absence of the half-step frequency relationship.
